what is the conversion time for a 12-bit adc with a clock frequency of 1 mhz?
The conversion time for a 12-bit ADC with a clock frequency of 1 MHz is 12 microseconds (μs).
What is conversion time?The conversion time for a 12-bit ADC with a clock frequency of 1 MHz is 13 microseconds.
An Analog to Digital Converter (ADC) transforms an analog signal into a digital signal.
The conversion time for an ADC (Analog-to-Digital Converter) can be calculated using the formula:
Conversion Time = (Number of ADC Cycles x Clock Period)
For a 12-bit ADC with a clock frequency of 1 MHz, each conversion requires 12 cycles of the ADC clock. The clock period can be calculated as the inverse of the clock frequency:
Clock Period = 1 / 1,000,000 = 1 μs
Therefore, the conversion time can be calculated as:
Conversion Time = (12 x 1 μs) = 12 μs
So the conversion time for a 12-bit ADC with a clock frequency of 1 MHz is 12 microseconds (μs).

28 grams of seeds cost $100 , and 14 grams of seeds cost $60. If you only have $70 and someone gives you $30 to buy 28 grams, how many grams of seeds would you give the person that gave you $30 if you paid $70?
Answer:
8.4 grams
Step-by-step explanation:
We have $70 to start and someone us another $30 for a total of $100. We pay $100 for 28 grams of seeds. If we assume the peron giving us $30 wants a fair share of the seeds, we would calculate an average cost per gram and use that to determine the grams of seeds that the $30 would have covered.
($100/28 grams) = $3.57/gram
($30/$3.57/gram) = 8.4 grams
Answer:
28 grams of seeds
Step-by-step explanation:
(This question is a little tricky)
Note that:
{28 grams of seeds = $100}
----------------------------------------
You have $70 already, and then someone gives you $30.
It means $70 + $30 = $100
So you have $100 now, you can buy 28 grams of seeds and give the person that gave you $30.

Answer:
63 square inches
Step-by-step explanation:
You already have the polgygon divided into two rectangles, so we will use them.
The top rectangle has the dimensions of 5 and 9.
The bottom rectangle has the dimensions of 6 and 3.
To find the area of a rectangle:
area = length x width
A = lw
The area of the top rectangle:
A = 5 x 9
A = 45 square inches
The area of the bottom rectangle:
A = 6 x 3
A = 18 square inches
To find the total area, add the two areas together.
45 + 18 = 63 square inches
Here is a rectangle with length 5 units and width 2 units.
1. What is the area of the rectangle?
2. Dilate rectangle ABCD from point A by a scale factor of 2. Calculate the area of the image.
3. Dilate rectangle ABCD from point A by a scale factor of 3. Calculate the area of the image.
This refers to the ratio between the scale of a given original object and a new object. It is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2.
Solving for the area and scale factor we have:
L= 5 units
W = 2 units
The area of the rectangle =L * WA = (5 x 2)
A = 10 square units.
If the rectangle is dilated from point A by a scale factor of 2, the area of the image:A= (Scale factor of L * W)* L * W
= (2 x 2 x 5 x 2)
A = 40 square units.
If the rectangle is dilated from point A by a scale factor of 3, the area of the image is:A= (Scale factor of L * W)* L * W
= (3 x 3 x 5 x 2)
A= 90 square units

what is the value of x in the equation (3x+5)/2=(5x+3)/3
Answer:
x = 9
Step-by-step explanation:
\(\frac{3x+5}{2}\) = \(\frac{5x+3}{3}\)
multiply both sides by 6 ( the LCM of 2 and 3 ) to clear the fractions
3(3x + 5) = 2(5x + 3) ← distribute parenthesis
9x + 15 = 10x + 6 ( subtract 9x from both sides )
15 = x + 6 ( subtract 6 from both sides )
9 = x
Answer:
\(x = 9\)
Step-by-step explanation:
\( \frac{3x + 5}{2} = 1 + \frac{5x}{3} \\ 3(3x + 5) = 6 + 10x \\ 9x + 15 = 6 + 10x \\ 15 = 6 + 10x - 9 \\ 15 = 6 + x \\ 15 - 6 = x \\ 9 = x \\ x = 9\)

To help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed.
the cutoff score that will make a student eligible for the program is approximately 94.8. Any student who scores below this cutoff will be eligible for the reading program
To determine the cutoff score, we need to find the score that corresponds to the bottom 5% of the distribution. Since the variable is normally distributed, we can use z-scores to calculate the cutoff. The z-score corresponding to the bottom 5% is -1.645, which represents the critical value for a one-tailed test at a significance level of 5%.
To find the cutoff score, we use the formula: cutoff score = mean - (z-score x standard deviation). Plugging in the values, we have: cutoff score = 122.6 - (-1.645 x 18) = 122.6 + 29.91 = 152.51.
Therefore, the cutoff score that will make a student eligible for the program is approximately 94.8. Any student who scores below this cutoff will be eligible for the reading program

For a sample with M = 50 and s = 12, what is the X value corresponding to z =-0.25? a. 46 b.47 c. 53 d. 54
Step-by-step explanation:
To find the X value corresponding to z = -0.25, we can use the formula:
z = (X - M) / s
where z is the standardized score, X is the raw score we want to find, M is the population mean, and s is the population standard deviation.
Rearranging this formula, we get:
X = z * s + M
Substituting the given values, we get:
X = -0.25 * 12 + 50
X = 47
Therefore, the X value corresponding to z = -0.25 is 47.
Hence, the answer is option B.
The X value corresponding to z = -0.25 is 47 (option b).
To answer this question, we need to use the formula for calculating z-scores, which is:
z = (X - M) / (s)
where z is the z-score, X is the raw score, M is the population mean, and s is the population standard deviation.
In this case, we are given the population mean (M = 50) and the z-score (z = -0.25). We also know that the population standard deviation (s) is 12.
We can rearrange the formula to solve for X:
X = z * s + M
Plugging in the values we have:
X = -0.25 * 12 + 50
X = 47
Therefore, the X value corresponding to z = -0.25 is 47. The answer is (b).
It's important to note that z-scores are a way of standardizing data so that we can compare different sets of data that may have different scales or units. In this case, we are using the z-score to find the corresponding raw score.

It takes 6.75 years for the population to reach 50,400 organisms and value of a is 12000 and b=1.146.
We know that the initial population is 12,000, so we can substitute this into the equation:
12,000 = ab⁰
12,000 = a
Therefore, a = 12,000.
Next, we need to find the growth rate (b) per year.
The population grows by 14.6% each year, which can be expressed as 1 + 0.146 (decimal form). So, b = 1.146.
Now we have the values of a and b:
a = 12,000
b = 1.146
To determine the number of years until the population reaches 50,400 organisms.
we can substitute P = 50,400 into the exponential model and solve for t:
50,400 = 12,000 × 1.146^t
Taking the logarithm of both sides can help us solve for t:
log(50,400) = log(12,000 × 1.146^t)
Using logarithmic properties, we can simplify the equation:
log(50,400) = log(12,000) + log(1.146^t)
t = (log(50,400) - log(12,000)) / log(1.146)
t = 6.75
Therefore, it takes 6.75 years for the population to reach 50,400 organisms.

When testing the iq of a group of adults, a researcher noticed that the correlation between iq and age was negative. Is this a guarantee that all younger people have higher iqs than older people?
The negative correlation between IQ and age guarantees that all younger people have higher IQ's than older people.
The strength of the linear link between two separate variables, x and y, is shown by correlation coefficients. A positive association is shown by a linear correlation coefficient larger than zero. Indicating a negative association is a value less than zero. The two variables x and y do not have any relationship when their values are 0, to sum up.
A positive correlation indicates that both variables move in the same direction when the correlation value is higher than 0. When is 1, it denotes a complete positive association between the two variables under comparison; when one variable rises or falls, the other one rises or falls in the same direction and by the same amount.
When the correlation coefficient is less than 0, there is a negative (inverse) correlation. This suggests that both variables are moving in the obverse direction. In essence, any reading between 0 and -1 denotes an opposing movement of the two securities. The connection is said to as fully negatively correlated when is equal to -1.
Thus, the negative correlation between IQ and age guarantees that all younger people have higher IQ's than older people.
